Dividing Daredevils

With my regular geometry class, I wanted to have an activity that they can get started with right way on the first day of school. I came up with them dividing shapes into similar figures using this worksheet below:

I think some students will divide into four congruent shapes while others will divide into four similar shapes. It can generate discussion about what the difference is and motivate some discussion on how these will be two huge concepts for the rest of the year.

Enjoy your remaining summer while it lasts!

Scatterplot Suspense

I have been thinking what I want my first days of school to be like and I want to know where my Algebra II students are in terms of how they are feeling about math. Since we talk about scatterplots and how to interpret them, I thought it might be interesting to put up the following grid on the board on the first day:

2z. Graph Yourself Picture

I will give each student a sticker (I was going to have them use their name but then I figured that this way I can keep it kind of anonymous) and have them paste it up where they feel they align.

I think this could work really well

  • I can learn how the class feels about mathematics in a general sense
  • I can incorporate our scatterplot intro in the beginning of the year with a real activity
  • I think students would be willing to discuss when I ask a question like “how many people think math is easy in this classroom?”

I like low-entry first day activities for algebra like this to get kids discussing and then hopefully change their opinions by the end of the year!
